Resolution

Width & Height

Controls the dimensions of the generated video in pixels.

Setting Range Default
Width 256-1280 512
Height 256-1280 320

Tips:

  • Both dimensions should be divisible by 64 for best results
  • Higher resolutions require more memory and time
  • Start with smaller sizes for testing

Common Aspect Ratios

Aspect Width × Height Use Case
16:10 512×320, 640×400, 768×480 Standard
16:9 768×432, 1024×576 Widescreen
9:16 384×640, 432×768 Portrait/Mobile
1:1 512×512 Social media
2.4:1 768×320 Cinematic

Frames

Number of Frames

Total frames to generate. More frames = longer video.

Setting Range Default
Frames 9-121 25

Duration calculation:

Duration (seconds) = Frames ÷ FPS

Examples at 24 FPS:

  • 25 frames = ~1 second
  • 49 frames = ~2 seconds
  • 73 frames = ~3 seconds
  • 97 frames = ~4 seconds

FPS (Frames Per Second)

Playback speed of the generated video.

Setting Range Default
FPS 8-30 24

Tips:

  • 24 FPS: Cinematic feel
  • 30 FPS: Smooth motion
  • 12-15 FPS: Animation style

Quality Settings

Inference Steps

Number of denoising steps. More steps = higher quality but slower.

Setting Range Default
Steps 10-100 40

Recommendations:

  • 20-25: Fast preview
  • 35-45: Good quality
  • 50+: Maximum quality

The quality improvement diminishes after ~50 steps.

Guidance Scale

How closely the model follows your prompt.

Setting Range Default
Guidance 1.0-20.0 7.5

Effects:

  • Low (1-3): More creative, may ignore prompt details
  • Medium (5-8): Balanced adherence
  • High (10+): Strict prompt following, may reduce quality

Recommended range: 5.0 - 10.0


Seed

Random Seed

Controls the randomness of generation.

Setting Range Default
Seed 0-2147483647 Random

Usage:

  • Same seed + same parameters = identical output
  • Leave at -1 for random seed each time
  • Save the seed of good results to reproduce them
  • Try seeds ±1 from good results for variations

Prompts

Main Prompt

Describe what you want to see in the video.

Best practices:

  • Be descriptive and specific
  • Include camera movement if desired
  • Describe motion and action
  • Mention lighting and atmosphere

Negative Prompt

Describe what you want to avoid.

Common negative prompts:

worst quality, low quality, blurry, 
jittery motion, distorted, 
watermark, text, logo,
static, still image

Presets

Presets provide quick access to common configurations:

Fast Preview

512×320, 25 frames, 25 steps

Quick testing, ~30 seconds

Standard

640×384, 49 frames, 40 steps

Good balance, ~2 minutes

High Quality

768×512, 65 frames, 50 steps

Best results, ~5+ minutes

Portrait

384×640, 41 frames, 35 steps

Vertical format for mobile

Square

512×512, 41 frames, 35 steps

Social media format

Cinematic

768×320, 49 frames, 40 steps

Ultra-wide aspect ratio


Performance Notes

Memory Usage

Approximate VRAM requirements:

  • 512×320: ~8GB
  • 640×384: ~12GB
  • 768×512: ~16GB

Generation Time

Rough estimates on M2 Max:

  • Fast Preview: 30-60 seconds
  • Standard: 1-2 minutes
  • High Quality: 3-5 minutes

Times vary based on:

  • Chip (M1/M2/M3/M4)
  • RAM amount
  • Other running applications
